c, recesive
Explanation:
x chromosomes are usually recesive
They are heavier because they absorbed the water.
Answer:
The difference is the shape and the jobs of the cell for example the white blood cell kills bad germs and sometimes helps scabs form and the red blood cell is to give oxygen to the body
Answer:
This experiment proved that DNA replicated semiconservatively; half the original polynucleotide is conserved in each of the two copies
Explanation:
Semi-conservative mode of replication means that the two strands of DNA unwind from each other, and each of themacts as a template for synthesis of a new, complementary strand. As a result, two formed DNA moleculesc ontain one original strand and one new strand.
Meselson and Stahl experiment showed this model by labeling the DNA of bacteria across generations using isotopes of nitrogen ( patterns of DNA labeling showed the mode of replication).
